Yokogawa Base Plate A2BN4D for Barrier for N-IO, MTL Barrier
A2BN4D Base Plate for Barrier This base plate allows for communication with the node interface unit via an F-SB bus by connecting the field signal to the terminal on the intrinsic safety (hereinafter I.S.) barrier mounted to this base plate. The Base plate for barrier, one of the components of the N-IO I/O unit (for Barrier) which is defined as A2ZN4DC for the system model, allows for mounting the I/O module and various I.S. barriers of MTL products from Eaton Electric Limited to it. The I.S. barrier has a field connection terminal (pressure clamp terminal) for connecting the field signal. The I/O modules can be mounted in a single or dual-redundant configuration. Up to 16 I.S. barriers can be mounted per channel. Furthermore, this base plate has a system power supply and field power supply interface and has a function to supply power to the I/O module from the Node interface unit via the Power supply cable for base plate (A2KPB00), and has a function to supply field power to the I.S. barriers by connecting the specified power line. The following shows the I/O module and I.S. barriers that can be mounted to this base plate. MTL’s I.S. barriers for Yokogawa Base Plate A2BN4D for Barrier for N-IO, MTL Barrier MTL4541Y, MTL4541YA, MTL4545Y, MTL4514N, MTL4521Y, MTL4523Y, MTL4573Y Number of components that can be mounted for Yokogawa Base Plate A2BN4D for Barrier for N-IO, MTL Barrier I/O module: 2 modules I.S. barrier: 16 barriers Connected the F-SB Bus Cable (A2KLF00) Weight for Yokogawa Base Plate A2BN4D for Barrier for N-IO, MTL Barrier
